GA-2100 CasiOak Strap Size — Adapter Required, 22mm After

The GA-2100 has no standard lug width — the resin case uses a proprietary integrated mount that takes only the stock band. A 22mm adapter converts the mount to standard spring bars, and after that the entire 22mm strap world bolts on.

FAQ

What size strap fits the GA-2100?

None directly — the stock mount is proprietary. Install a 22mm adapter first, then any 22mm strap fits.

Do GA-2110 straps fit the GA-2100?

Both use the same resin mount family and the same 22mm adapter route.

Can I put a strap on a GA-2100 without an adapter?

No — the integrated band mounts with pins inside the case; there are no standard spring-bar holes until an adapter is fitted.
